PROCESS OF MELTING AND APPLYING MARINE GLUE, 81.0.

SPECIFICATION forming part of Letters Patent No. 761,300, dated. May 31, 1904. Application filed January 24:, 1901. RenewedFebruary 3, 1903. Serial No. 141,737. (No specimens.)

To all whom it may concern:

Be it known that I, ARTHUR J EFFERY, gentleman, a subject of the Queen of GreatB'ritain and Ireland, and a resident of Muster Green, Haywards Heath, county of Sussex, England, have invented certain new and useful Improvements in Processes of Melting and Applying Marine Glue and "other Convenient Substances, of which the following is a specification.

This invention relates to improvements in process for melting and distributing marine glue. and other similar convenient substances.

The improved apparatus consists of a rectangular-shaped vessel in which the material to be melted is placed. This vessel is open at the top, and the'bottom is made sloping,

flat in shape at one end and semicircular at the other. A. series of tubes run from the front to back of said vessel at or near the lower part of the same. The said vessel fits into another U-shaped vessel sufiiciently large to allow a space all round the said vessel and extending to about half the height of the said inner vessel and is so constructed as to form a space all over the lower part of the inner vessel, so that a heating-chamber is provided for the outside of thelower part of the inner vessel as well as through the tubes aforesaid. The heat is provided by any convenient means as, .for instance, the heat of a petroleum-lamp attached to one end of the outer vesselthe heated air thus generated passing through a circular opening provided in the outer casing.

A portion of this heated air circulates around I the lower part of the inner vessel and the remaining portion goes through the tubes aforesaid, so that a large amount of heating-surface is by this means provided for the purpose of heating and melting the marine glue or other similar substance. The opposite end to that to which the lamp is fixed is perforated with holes and a baifleplate for the escape of the heated gas is provided, and also a branch or outlet-pipe of con venien't diameter is provided at the bottom ofthe outer vessel as another outlet for the heated gas. An outlet branch pipe is provided at the lower end of the inner vessel, which leads down into the outlet-pipe of the outer vessel and terminates in a special sluice-valve, which consists of two disks one and so constructed that when the disk is moved .sidewise it cuts off the flow of melted marine glue or other substance by covering the end of the branch pipe from the melting-pot or inner vessel; butwhen the sliding disk is eX- actly over'its fellow disk the liquid flows through and out at the tapering branch pipe aforesaid onto the deck or floor to be operated on. The whole apparatus may be mounted on a carriage with V-edge wheels, which may be made to run in the seams of the floors or decks, and thereby guide the apparatus so that the end of the tapering branch outlet may be exactly over the seam to be filled with the substance. The fiow of the liquid glue may be regulated by means of a lever and handle attached to the carriage in any convenient manner.

The marine glue or substance to' be melted is placed in the inner vessel, as before mentioned, the lower portion resting on the tubes aforesaid, which become heated by the gas generated by the petroleum-lamp, and the melted substance flows down the sides of and between the tubes and falls-onto the lower part of the'vessel, which is also raised in a similar manner to a hightemperature, and-continues to flow down into the branch pipe, its liquid state being uniformly maintained till it is led into the seams of the floor.-

In order that this invention may be readily understood, reference is made to the accompanying drawings, in which.

Figure 1 represents a side sectional elevation of the apparatus; Fig. 2, an end view, partly in section; Fig. 3, a plan of-the same, also partly in section. Figs. 4 and 5 are respectively enlarged side section and front view of the regulating-valve or sluice for the supply ofthe melted marine glue when in use.

The same letters refer to the same parts in the several views.- I

A is the melting pot or rectangular-shaped vessel, which is open at the top B, and the bottom is made sloping and flat in shape at the end C and semicircular at the other end D.

E E E E are tubes running from back to front of the said vesselA.

F is the outer vessel, of a size to allow of airspace at G at both the sides and ends of the vessel A for the convenient passing of the heated air or gas through the apparatus.

H H are vent-holes in the sides and end of the outer vessel F. I I are baflie-plates for regulating the same.

J is a branch pipe or circular opening for receiving the funnel or chimney of the petroleum-lamp K.

L is the outlet-tube, tapering in diameter, for conveying the melted substance to the outlet-valve or sluice M, which consists of two disks N N, sliding one upon the other, and in this way opening or closing the outlethole 0 in the manner shown by the dotted lines at P. WVhen the valve or sluice is open, the liquid glue flows out through the spout Q, and into the seams of the floor or deck or where it is desired to be conveyed. The action of the aforesaid valve or sluice is regulated by the wire rod R, passing through the tube S, attached to the handle-frame T, terminated in the loop or handle U and controlled by the hand of the operator who is using the apparatus. The whole apparatus is mounted on a carriage-frame V, having V-shaped wheels or runners W, which are placed at a slight angle, as shown at X, for conveniently running in the seams of the deck or floor.

The heated gas generated by the petroleumlamp K passes partly through the tubes E E E E and partly around the vessel A and escapes either through the vent-holes H H or through the outer tube Y, surrounding the delivery-pipe L. A large amount of heatingsurface is by this means provided, effectually heating and melting the marine glue, which is placed in the vessel A and lies on the tubes E and is gradually melted and flows down the sides of and between the said tubes to the sluice or valve M, the liquid state of the substance treated being uniformly maintained till it reaches the seams of the deck or floor or the place to which it is directed.

Having now described my invention, what I-claim as new and desire to secure by Letters Patent, is

l. The process herein described of applying an adhesive to floors or decks, which consists in supporting the adhesive in a movable vessel, maintaining the solid adhesive above and separate from the fluid adhesive, leading aheating medium alongside the fluid adhesive, and conducting the fluid adhesive to the floor as the vessel is moved.

2. The process herein described of applying an adhesive to floors or decks, which consists in supporting the adhesive in a movable vessel, leading a heating medium under pressure alongside the vessel and conducting the fluid adhesive from the vessel to the floor as the vessel is moved.

3. The process herein described of applying an adhesive to floors or decks, which consists in supporting the adhesive in a movable vessel, maintaining the solid separate from the fluid adhesive, leading a heating medium through the division between the solid and fluid adhesive, surrounding the lower portion of the vessel with a heating medium, conducting the adhesive from the bottom of the vessel to the floor, and diverting a portion of the heating medium to surround the conducted fluid adhesive in its passage from the vessel to the floor.

4. The process herein described of applying an adhesive to floors or decks, which consists in supporting an adhesive in a movable vessel, leading a heating medium alongside the vessel, guiding the movable vessel by ongaging therewith the seams of the floor, and conducting the fluid adhesive to the seams of the floor. 4

In witness whereof Ihave hereunto set my hand in presence of two witnesses.
